    Creative geotechnical photography

    Inspired by her surroundings at RHS Rosemoor, where she was carrying out the ground investigation for a new educational facility, and with one eye on the Ruddlesden geotechnical site photograph of the year competition, Catherine Greed got creative with her site photography recently, framing the dynamic sampling rig within the last of the summer flowers.

    Pre-Purchase Phase 1 Geotechnical Assessment Provides Cost-Effective Information

    Ruddlesden geotechnical were commissioned to undertake a Phase 1 Geotechnical Assessment on behalf of a national housebuilder at an existing golf course in Dorset. Following a review of the desk study information and the consultation of historical maps, geological maps and memoirs, a walkover survey of the site was undertaken. This information allowed a ground model to be produced, which was used to identify the geotechnical risks and current uncertainties with regards to the proposed residential redevelopment of the site. The site was zoned, based on the anticipated ground conditions, and recommendations covering foundations, excavations, surface water drainage and slope stability were provided. The findings of the Phase 1 informed the scope of works for the Phase 2 deotechnical investigation and contamination assessment and ultimately provided the client with an understanding of the development constraints, opportunities and forecasted development costs for the site, prior to committing to the purchase of the site.

    Plate Bearing Testing for Wind Turbine, Devon

    Ruddlesden geotechnical have recently undertaken plate bearing testing at a number of farms in Cornwall to validate geotechnical parameters, provided as part of a previous geotechnical investigation, used in the design of the wind turbine. Ruddlesden geotechnical liaise with the client and construction team to undertake the testing as soon as excavation is complete, to ensure the ground to be tested is relatively undisturbed, representative and as not to delay the construction phase. Careful planning can allow other aspects of wind turbine construction, including crane pads and track ways, to be validated, to save time and ultimately construction costs.
